INTERIOR IBRACING F SILOS.

To all whom it may concern:

is to provide wooden stave silos With cer-' tain adjustable and economical braces which are easily and quickly applied, and which will be highly eflicient in preventing the blowingdown or collapsing of the silos when empty and which can be easily and quickly removed as the silos are being filled.

-One object is to provide interior braces which will prevent the flattening of the sides of a circular silo.

Similar characters of reference are used to; indicate the same parts throughout the several views.

Sections of a silo are shown to illustrate the improvements applied to the silo. The

silo is set on a base 1 and constructed of vertical Wooden staves 2 which are usually oined by tongue and groove joints 3. The main brace 1 is a continuous brace which may be made of a single piece of L-shaped angle iron or as many pieces as may be de- ,s1rable or convenient for ad usting the brace. The ends of the brace 4 may be connected by lapping the same as shown in Fig,

It isap- 2 and bolting the same together. parent'that channel iron may be used instead of the L-shaped iron. The lapped portions of the angle iron are to be provided with a plurality of holes 5 so that the circle of the main brace may bevaried to adapt the same to different sizes of the inner walls of silos. The ends of the brace 4 can be lapped on each other and the holes in the two ends ,can be made to register with each: other so that the bolts 12 can be inserted to secure the ends together. The brace 4 can be mounted on the inner wall of the silo at as many points as may be necessary and the braces can be mounted as the ensilage is used or removed so that a person can stand on the ensilage and mount the brace and the brace can be removed as the silo is being filled. When ensilage is filled in up to a brace the brace can be removed and no ladders of any kind will be necessary. The brace 4 may be mounted with brackets (3, such as shown in Figs. 1 and 6, or with such devices as are shown in Fig. 7. The main brace 1 can be braced with a number of sectional orcross braces 7 and 8. Holes may be made in the base flange of the brace +1 so that the bent ends of the braces 7 and 8 can be inserted as shown in Fig. 4 or plates 9 may be attached to the base of brace l and the braces rods 7 and 8 are provided with turn buckles 7 and 8 caught in the lates 9. The brace 10 for adapting braces and 8 to the brace 4. Guy wires or rods 11 may be caught in the attaching U-bolts 11 as shown in Fig. 6. It is apparent that the cross braces 7 and 8 may be constructed of any suitable material such as rods or cables.

The adjustment of the circular brace is made preferably only at the front of the silo. The vertical flanges of lapping portions of the brace 4 c'anbe cut awayand the ends lapped on each other and secured.

together by bolts 12. The "'endsfofp the braces are made adjustable by providing a T plurality of holes. The partsof tliebrace Y which lap on each other may be-fur'ther braced against inward displacement by lugs 1 1, as shown in Figs. 2 and 3. -The extreme ends 15 of the brace 4: may extend alongbeside the flange 16 of the' brace 4. One of the i braces at can bepermanently attached to the interior of. the silo at the upperend because such braces do not interfere with theifilling Below the upper end, the braces of the'silo.

A plate 27'may engage'the ends of the U-bolts 26 to serve as washers for nuts 28. Instead of fastening the ends of the circular brace 4: together .as heretofore de-' scribed, the ends of the brace 4.- maybe made sides of the silo.
